I'm guessing just in the rear storage area for ease... Now I just need to find a case that isn't huge and ugly.. I'm using a standard ATX mobo (probably, that's what I will most likely have laying around)..

A snip here, a few well placed holes and I've got an in-dash double din case. You could make your own by hand. Just needs some sheet aluminum and a few tools. He has a sheet metal break available to him, but that's not necessary.
